==Character sets==
Due to its origins on [[IBM]] [[IBM Selectric typewriter|Selectric]]-based [[teleprinter]]s, APL symbols have traditionally been represented on the wire{{jargon inline|date=August 2025}} using a unique, non-standard character set. In the 1960s and 1970s, few terminal devices existed which could reproduce them, the most popular ones being the [[IBM 2741]] and [[IBM 1050]] fitted with a specific APL print head. Over time, with the universal use of high-quality graphic display, printing devices and [[Unicode]] support, the APL character font problem has largely been eliminated.
 
===Character repertoire===
IBM assigns the following character IDs (GCGIDs) to APL syntax, which are used in the definitions of its code pages.<ref name="cs963"/><ref name="cs963pdf"/><ref name="slgcgidchart"/>

===Unicode===
Most APL symbols are present in Unicode, in the [[Miscellaneous Technical]] range,<ref>{{cite web |url=http://unicode.org/charts/PDF/U2300.pdf |format=PDF|title=The Unicode Standard 5.1 Code Charts: Technical Symbols U+2300-U+23FF |access-date=October 12, 2008 |work=Unicode Standard 5.1 |publisher=[[Unicode Consortium]] |archive-url= https://web.archive.org/web/20081002004650/http://www.unicode.org/charts/PDF/U2300.pdf |archive-date= 2 October 2008 |url-status= live}}</ref> although some APL products may not yet feature Unicode, and some APL symbols may be unused or unavailable in a given vendor's implementation.
 
As of 2010, Unicode allows APL to be stored in text files, published in print and on the web, and shared through email and instant messaging. Entering APL characters still requires the use of either a specific [[input method editor]] or keyboard mapping, or of a specific touch interface. APL keyboard mappings are available for free for the most common operating systems, or can be obtained by adding the Unicode APL symbols to existing keyboard map.
Line 1,963 ⟶ 1,971:
Missing from Unicode are the traditional [[underlining|underscored]] alphabetic characters included in some of the APL code pages; their usage has been eliminated or deprecated in most APL implementations. These were produced on APL printing terminals by over-striking a straight capital letter with an underscore character. Some tables show them simulated with underlined and italic markup, not listing Unicode mappings.<ref name="tachyon310"/>
 
IBM assigns them GCGIDs as "LA480000" (which they name "A Line Below Capital/A Underscore (APL)"), "LB480000" ("B Line Below Capital/B Underscore (APL)") and so forth, under the "L" series used for Latin letters.<ref name="cs963" /> The use of an even number (48) rather than an odd number (47) is due to being uppercase: compare the use of SD110000 for a lone acute accent {{code|´}}, LA110000 for the lowercase {{code|á}}, and LA120000 for the uppercase {{code|Á}}.<ref name="cp1252">{{cite web |url=ftphttps://ftppublic.softwaredhe.ibm.com/software/globalization/gcoc/attachments/CP01252.txt |title=Windows, Latin 1 |id=CPGID 01252 |publisher=[[IBM]]}}</ref> They are included in IBM's [[Private Use Areas|private use area]] scheme, encoded in reverse‑alphabetical order in the odd-numbered code points from U+F8BF to U+F8F1.<ref name="unicodenam"/>
 
Homologous uses of 47 include the "SD" (diacritic) series GCGID SD470000 for "Line Below/DiscontinousDiscontinuous Underscore"<ref name="cs969">{{cite web |url=ftphttps://ftppublic.softwaredhe.ibm.com/software/globalization/gcoc/attachments/CS00969.txt |title=OCR B |id=GCSGID 00969 |publisher=[[IBM]]}}</ref>—i.e. [[macron below]], distinct from the ASCII underscore which is SP090000 ("Underline/Continuous Underscore")<ref name="cp1252"/>—and the "A" ([[Arabic script|Arabic letter]]) series GCGID AD470009 for the [[ḏāl]],<ref name="cp1256pdf">{{cite web |url=ftphttps://ftppublic.softwaredhe.ibm.com/software/globalization/gcoc/attachments/CP01256.pdf |title=Windows, Arabic (PDF) |id=CPGID 01256 |publisher=[[IBM]]}}</ref> for example. Unicode's [[Latin Extended Additional]] block includes the following capital "Line Below" characters with the macron below diacritic, for Semitic transcription (it includes a pre-composed ẖ only in lowercase):

==Keyboard layout==
NoteThere theare mnemonics associating an APL character with a letter: {{keypress|?}} (''question mark'') on {{keypress|Q}}, {{keypress|⋆}} (''power'') on {{keypress|P}}, {{keypress|ρ}} (''rho'') on {{keypress|R}}, {{keypress|⊥}} (''base value'') on {{keypress|B}}, {{keypress|⊤}} (''eNcode'') on {{keypress|N}}, {{keypress|∣}} (''modulus'') on {{keypress|M}} and so on. This makes it easier for an English-language speaker to type APL on a non-APL keyboard, providing one has visual feedback on one's screen. Also, decals have been produced for attachment to standard keyboards, either on the front of the keys or on the top of them.
